A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston disposed within a cylinder. The piston is configured to pressurize at least one pumping chamber. A motor is coupled to the housing and connected to the reciprocating piston fluid pump to actuate the piston. A wobble assembly connects the motor to the piston of the reciprocating piston fluid pump. A spray tip connected to an outlet of the at least one pumping chamber.

Portable airless sprayer

A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston. The piston is configured to pressurize at least one pumping chamber. A motor is connected to the reciprocating piston fluid pump to actuate the piston. A spray tip connected to an outlet of the at least one pumping chamber.

A fluid dispensing device comprises a housing body, a fluid container, a reciprocating piston fluid pump, a primary drive element and a spray tip. The housing body is configured to be carried and supported by an operator of the hand held airless fluid dispensing device during operation. The fluid container is supported by the housing body. The reciprocating piston fluid pump is coupled to the housing body and comprises at least two pumping chambers configured to be actuated out of phase by at least one piston. The primary drive element is coupled to the housing body and connected to the reciprocating piston fluid pump to actuate the at least one piston. The spray tip is connected to an outlet of at least one of the pumping chambers.

A portable airless sprayer comprises a housing, a motor, a pump, a spray tip and a trigger. The motor is mounted to the housing. The pump is mounted to the housing and is driven by the motor. The spray tip assembly receives pressurized fluid from the pump. The trigger is configured to actuate the spray tip assembly and activate the motor. A method of operating a portable airless sprayer comprises moving a lever over a stroke, displacing a valve pin, and activating a motor. The valve pin is displaced with the lever to actuate a spray valve. The motor is activated with the lever to drive a pump that provides fluid to the spray valve.

A sprayer attachment for a hand-supported power tool comprises a motion converting mechanism, a pumping mechanism, a spray assembly and a housing. The motion converting mechanism has an input shaft. The pumping mechanism is driven by the motion converting mechanism. The spray assembly is fluidly coupled to the pumping mechanism. The housing assembly couples the motion converting mechanism, the pumping mechanism and the spray assembly. The sprayer attachment may further comprise an anti-rotation bracket extending from the housing. The sprayer attachment may further be coupled to a handheld power tool, such as a cordless drill or a reciprocating saw, with the anti-rotation bracket.

A roof anchor comprises a pliable member including an interconnecting portion interconnecting a first portion and a second portion. The first portion and the second portion each include a securing portion with a plurality of apertures and a connecting portion with an aperture. A first notch and a second notch are proximate the junctures of each securing portion and connecting portion. The first notch and the second notch extend inward from opposing sides and toward proximate a middle of the respective first and second portions, and an aperture is between each first notch and second notch.
